Trying to decide 3.8 0r 4.6?

[Genny46PM]

Besides the horse power/torque difference between 3.8 V6 and 4.6 V8, it is important to note the power train dynamics is not identical. The 3.8 has Lamda V6 engine with Aisin transmission where as 4.6 has Tau V8 engine with ZF transmission.
I've owned 2009 3.8 for about 6 months until it was upgraded to the 2010 4.6. In my subjective opinion, the power delivery and the ride is substantially smoother in V8 than V6. The short test drive at the dealership won't help distinguish the difference. The difference can only realized if one can drive both cars in similar duration.

Every day I am amazed by the smooth power of the 4.6 V8. It is silky smooth and incredibly powerful. It is so smooth it almost feels like an electric motor. It is by far the best and most powerful car I've ever owned.

I used to own a Toyota Supra that had a lot of power, but it wasn't in the same league with the Genesis. I've driven my wife's BMW 330xi, but it can't touch the Genesis. My wife used to own a twin-turbo Dodge Stealth; it had a lot of power once you got the turbines spinning at high RPM, but it was sluggish at low RPM coming off a stop. There's nothing like a big V8 to get you moving.

I've always held the position "You can't have too much power in a car". Well, the 4.6 may not be too much power, but it is more than enough for me.

I find it challenging to drive my Genesis below 40 MPH. The throttle is barely cracked. The difference in foot position between 30 MPH and 40 MPH is barely perceptable. That's one of the reasons I use smart cruise control on 40 MPH roads. Heck, even at 75 MPH, it's only turning at 2000 RPM.
